I respect your need for an application to acutally BUY music, but would it be too much to ask to make your DB of what's available and at what price without me having a mac or windows machine with the downloaded app? I guess that does cut into your "take over the world" plans, but it might sell you more music.

The iTunes app is like a virus too. I got my last machine accidentally infected and had a terrible time trying to remove all of its parts after I couldn't figure out how to prevent it from running. It inserted almost as many fingers in my stew as anti-virus software does.We need a small, transparent, runs-only-when-you-ask-it-to app (like AdAware for spyware) to protect against, and root out these invasive weeds.

Except for apps I start, this machine (Tranquility) has only 28 processes running, but that takes constant vigilance to protect against ambuscades like iTunes.
